"With very few exceptions, open end wrenches are not used in manufacturing."

Mike, I suspect there are a lot of good reasons for this.

I watched the video on the VW Phaeton plant in which the wrenches are all hooked into the computer. One wrench is used to secure a set number of nuts or bolts in each work station and the computer keeps track of the number of operations and the torque values.

I suggest if you can get a torque wrench on it to ensure proper securing of the fastener, you can ditch your open end wrench and use a powered torque wrench.
